WASHING-MACHINE.

'1'0 a whom it may concern;

"Be it known that we, CHARLES W. GRAMER and HARRY O. HAAK, citizens of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania,

have invented certain new and useful Imrovements in Washing-Machines and we do liereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled .in the art to which it appertains to make and use the same. V v

This invention relates to improvements in washing-machines, and particularly to an oscillatin tub.

The 0 ject in view is the provision of means for securing maximum leverage and facilitating actuation of a tub for providing for resili ency of movement of such tub. 2 With this and further objects in view the invention comprises the combination of a pivotally-mounted tub, a spring engaging the outer surface thereof, a lever engagin said spring and pivoted to the pivot of sai tub, 2 5 and means for facilitating actuation of the lever.

It further comprises certain other novel constructions, combinations, and arran ements of parts, as will be hereinafter fully escribed and claimed.

In the accompanying drawings, Fi ure 1 is a plan view of the su porting-legs an motor, certain other parts t at lie above them being indicated by dotted lines. Fig. 2 is an in- 5 verted plan view of the parts illustrated in-- dotted lines in Fi 1. Fig. 3 is atransverse' vertical section ta en on the plane of line 3 3 of Fig. 1. Fig. 4 is an enlar ed detail fragmentary erspiective view i lustrating the rac et and surrounding parts. Referring to the drawings by -numerals, 1 indicates the bottom, and 2 the sides, of a tub, which we have referred to as a tub throughout this specification and the ap endant,

claims; but we wish it clearly un erstood that by theterm tub we mean any elementwhose oscillation accomplishes a useful function. A bracket 3 is secured to side 2 and bottom 1 and is formed with a projecting 5o hook 4, designed to be engaged by the eye 5 of ahelical springfi, which spring 6 is provided at its opposite end with an eye 7, en-

aging an eye 8 of anactuating-lever 9. The ever 9 is formed with a sleeve 10 at its inner Specification of Letters Patent.

end, loosely surrounding and ivotally engag- 5 5v ing a vertical shaft 1 1, suitab y ournaled in a bearing 12, fixed to supports-13 13. The shaft 11. extends upwardly through the bot tom 1 and may be connected to the same in any desired manner. I

Formed integral with or fixed to the sleeve 10 and extending from the'same on the opposite side from lever 9 is a segmental rack 14, 7 adapted in operation to mesh with a rack-bar 15, fixed to the outer end of a piston-rod 16, carryin a piston of any ordinary t pe Within a cylin er 18. The outer edge 0 the rack .bar 15 engages and i'sguided by asuitable limitingbracket 19, which extend. above the upper surface of said rack-bar and prevents lateral play thereof. The end of the cylinder 18, through which the piston-rod 16 projects, is closed by a casing 20, surrounding said rod, and a lubricant-receptacle 26.is arranged to sup ly lubricant to thepiston-rod 16 and is pre erably formed with any suitable capi27.

' A supply-pipe 29 communicates wit one end of the cylinder 18 for supplying pressure to one side of the piston therein, and a similar pi e 30 communicates with the opposite end 0 said cylinder for supplyin pressure to the opposite side of said iston, t esupply of pressure being controlle by a suitable valve "31 of the three-way type adapted to be oscillated for admitting pressure through one of the pipes29'or 30, while permitting exhaust through the other of said pipes, rocking or oscillating of the valve 31 serving to alternately admit ressure to the opposite sides of the piston in t e cylinder 18 for reciprocating thesame', and said oscillation of the valve 31 being accomplished by the engagement of lugs 34 and 35, projecting from the stem of said valve, by suitable tripping-fingers 32 and 33. The fingers 32 and 33 are exact'du plicates of each other and are carried by radially-extending arms 36 and 37, fixed to the under surface of the bottom 1', the finger 32 beirig a greater distance from the axis of movement of said bottom than is the finger 33 whereby I in operation the fin er 32 is adapted to strike the lug 35 and t e finger 33 is adapted to enga e the lug 34, the lugs 34 and 35 being in dierent vertical planes, with the lug 34 nearer the pivot of the bottom 1; Each of the fingers 32 and 33 is pivotally supported and provided with a shoulder at one side of its pivot, each-of said fin-' gers being thus free to swing away l'romthe respective lug of valve 31 during its rearward marvel, while the shoulder of each of said gersiefliectually prevents therespectivc finygers from passing the corresponding lug of valve- 31 in its forward travel without throwing the same. ,lates 45 15 rise from the support 13 in the rear of the bracket 19 and are spaced apart a andfiared outwardly and areadapted par-" ticularly for the reception of a bolt 46, slidiipigly carried by the bottom 1., said bolt being it apted to be passed between the plates 45 for locking the bottom positively against 1.5; movement. l A lug 47 depends from the arm 37 and extends to a plane below the horizontal plane of the upper edge of one of the plates 45, whereby in operation should the bottom. 1 swing too far in one direction the said lug I will engage said plate and prevent the bottom from moving to such an extent as to cause the tri' ping-finger 33 to pass the cylinder 18. If t e finger 33 should pass the cylinder 18, it will be readily observed that further movement of the bottom 1 would be rendered impossible, due to the fact that while finger 33 could swing in a direction for permitting the same to pass over the cylin- 0 der-18 while the bottom 1 is moved in one direction said fingers cannot swing in the opposite direction and could not permit the return movement of said bottom. Therefore the lug 47 is very essential for preventing 35 possible accident, although it is our intention to prevent the swinging of the bottom 1 to a degree for causing the lug 47 to engage the plate 45.

In operation fluid-pressure is admitted 0 from any suitable source through one of the passa es in valve 31 into pipe 29 and thence into t e cylinder 18, throwing the piston to the opposite end thereof to that in which the same is located when in the position indiygic ated in Fig. 1. This movement of the piston causes rack in meshing with the teeth {of segment 14 to actuate said segment and swing the same upon the shaft 11 as a ful- I Scrum, whereby the lever 9 will be caused to go travel through the arc of a circle and move ment is imparted from said lever through the spring 6 and bracket 3 to the tub-carrying bracket, the spring 6 serving to take up any sudden jerks and to produce a resilient movement of said tub, cushioning and effecting a recoil of the same at the end of the stroke of the lever 9. When' the piston has reached the limit of its movement, the tub actuated therebywill have been given sufficient momentum to partially expand the spring 6; which spring after overcoming such momenin retracts and starts the said frame in reverse movement. Just before the tub arrives at the extreme of its first moveagent, assuming the machine to have started carrying means for transmitting movement with the parts in the position indicated in Fig. 1, the latch 32 will engage lu and throw the valve 31 into a position 'or opening communication between the pressuresupply and pipe 30, said pipe 30having'previously been in communication with that passage in said valve 31 leading to the exha'ust. When the valve 31 has been thrown, as stated, the pipe 29 is caused to register with-that passage in the valve31 now communicating with the exhaust, and the admission of pressure through pipe 30 into cylin- 'der18 will cause the piston therein to travel I back to its former position, which return movement effects actuation 0f the segment 14: through the operation. of the rack 15. As the segmental rack swings back to its former position the lever 9 is caused to move back to its original. position, and movement is imparted through sprin 6 to the tub e'ngaged by the same, whie tub during its return movement gains sufiicient momentum for partially expanding said spring 6 at the end of said return movement, whereby the tub is given, by the retraction of the spring, a start on its next oscillation. Just before the said tub reaches the limit of its movement the latch 33 engages lug 34 and swings the valve 31 to its original position, opening communication of pressure to pipe 29 and opening the exhaust to pipe 30. The l operation may thus be automatically continued as long as desired, the tub being back andfiforth with a cushioning effect at the close or each stroke of the piston. It will be observed that the segmental rack 14 constitutes one portion and the arm heretofore described as lever 9 constitutes the other portion of the actuating-lever engaged by the spring 6, the said shaft 11 forming the fulcrum for the lever madeunp of the two parts mentioned.

Having thus fully described our invention, What weclaim as new, and desire to secure by 7 Letters Patent, is- 1 1o 1.
